Subject: Re: [PATCH v2 00/91] drm/vc4: Support BCM2711 Display Pipelin
Hi Maxime,
Thanks for your V2 patch series! I'm testing it.
This patch series is applied upon mainline kernel 5.7-rc2 cleanly and built.
System can boot into console text mode, but no graphic UI.
Get the error in vc5_hdmi_phy_init(), and full dmesg is at [1]:
